Medium Wall Direct Burial Heat Shrinkable Tubing

For direct burial of heavy duty electrical cable, where environmental protection is necessary. Tubing is supplied with an adhesive layer, adding a water tight seal to the strain relief the tubing provides. When exposed to heat (usually a bit lower than the activation temperature of the heat shrink), the inner layer begins to flow (just like a hot melt glue). When the tubing shrinks and cools down, the inner layer forms an adhesion layer between the tubing and the component or wire. This provides a watertight seal, protecting the connector and/or wire in direct burial and submersed applications
